EDWARD F. MCHU'GH, 'OF KINGSTON, PENNSYLVANIA INTERLOGKING STILL OR JAMB CC JVEBING Application filed July 24,

This invention relates to an interlocking 'sill or jamb covering designed primarily for use in connection with ventilating sashes employedupon store fronts for supportin plate I glass windows, and has for its object provide, in a manner as hereinafter set forth, a covering interengag'ing with the front of the sash and acting'to protect the sill or jamb from rain, moisture, sleet and snow and fur- 'ther functioning as a means for directing otf moisture or water drained from the sash both interiorly and exteriorly thereof.

A further object'of the invention is to provide, in a manner as hereinafter set forth, a sillo'r jambcovering'including means adapted to abut the bottom of the sill or jamb and means adapted to be engaged by the sash for locking the covering in snug position with respect to the sill or jamb without the employment ofholdfast devices for extension throughthe sill. V I

A further object of the invention is to .provide, in a manner as hereinafter set forth, a sill or jamb covering having its lower portion constructed in a manner to provide for the passing off therefromof rain, snow, sleet and moisture in a manner to prevent the same from contacting with the bottom of the sill or jamb, and with the covering formed in a manner/whereby the amount of material required therefor is materially reduced with respect to the amount of material employed for the sill or jamb coverings now generally used, under such conditions materially reducing the cost of installation.

A further object of the invention is to provide, in a manner as hereinafter set forth, a sill or jamb covering acting as a vprotector therefor and further capable of being locked in position by a sash employed upon store fronts for supporting plate glass windows.

Further objects of the invention are to pro vide, in a manner as hereinafter set forth, a sill or jamb covering which is simple in its construction and arrangement, strong, durab le, compact, thoroughly efiicient in its use, conveniently applied to the sill and comparatively inexpensive to manufacture.

Figure 6'is a vertical sectional view of still another modified form of covering showing the adaptation thereof withrespec't to asill, sash and glass.

Figure 7 is a perspective view of the moditied form of covering shown in Figure6 and further illustrating in perspective the back member of the sash which associates with the covering for locking the latter. The covering and back member are disassembled.

A covering in accordance with this invention is constructed of a single length of material of the desired gauge, preferably sheet copper, but 'it is to be understood that the covering can be manufactured from any suitable material.

The material from which the covering is formed is i'mperforate and as shown in Fig- 96 ures 1 to 3, it is shaped to provide a hori- 'zontal and a vertical part 1, 2 respectively, and with the latter depending from the outer side of the former. The partsl, 2 are to conform respectively to the shape of the top 100 and front of the sill 3 and to snugly engage the same when the covering is in position.

The part 1 is of less width than that portion of the sill 3 and the part 2 of greater height than the sill 3, and the latter is rabbeted on its top, as at 1, to provide a shoulder 5 adjacent the front of the sill. Seated in the rabbeted portion 1 and abutting the shoulder 5 is the part 1 which preferably has its upper face flush with the non-rabbeted portion of the top of the sill.

The part 2 depends below the sill and terminates in a vertically disposed leg 6, which opposes and is spaced from the outer face of the part 2. The leg 7 terminates at its upper end in a rearwardly directed, right angularly disposed flange 7 which when the covering is mounted in position abuts against the lower face of the sill 3. The bend 8 between the leg 6 and part 2 provides a rounded drip edge which is positioned below the bottom of the sill 3.

As illustrated the parts 1 and 2 are disposed at right angles with respect to each other and the part 1 projects rearwardly from the top of the part 2 and the rear side of the part 1 is formed with a vertically disposed flange 9 which is integral therewith and projects a substantial distance above the non-rabbeted portion of the top of the sill 3.

The leg 6, in connection with the flange 7 )rovides a resilient latch for securing the lower portion of the part 2 in position with respect to the sill3. The flange 9 coacts with certain elements of the ventilating window sash to be presently referred to for locking the part 1 in position with respect to the top of the sill 3. By the construction referred to the covering at two spaced points is provided with means for securing it in position, one of said means being the flange 9 and the other being the leg 6 in connection with the flange 7. The parts 1 and 2 are imperforate and owing to the construction referred to the covering is secured in position without the employment of holdfast devices to extend through the covering and engage in the sill 3.

The sill covering, forming the subject matter of this invention, is illustrated by way of exam le in connection with a ventilating sash flflr supporting a plate glass adjacent the backing stop 11 which is mounted on the sill 3 rearwardly of the non-rabbeted portion of the top thereof.

The ventilating sash for the plate glass 21 embodies a back member 12 formed from a single len th of sheet metal of the desired width and gauge and shaped to provide a vertical part 12 of appropriate width standing on its lower longitudinal edge. The part 12 corresponds in width to the thickness of back sto 11 so the upper edge of part 12' will be ffilsh with the upper face of stop 11. The art 12 is termed the body portion of mem r 12.

The part 12 at its top merges into a forwardly directed, downwardly inclined part 13 which terminates in a vertically disposed flange 13 to provide in connection with part 13 a combined clamping member and gutter. The part 13 is co-extensive with and of materially less width than part 12. The flange 13 is co-extensive with part 13 and has its top edge arranged in alignment with the top edge of part 12. The part 13 is formed with a plurality of ventilating or drain openings 1 1.

Extending forwardly with respect to the lower portion of part 12 and at right angles thereto is a horizontally disposed part 16 which constitutes a cushion. Depending from the rear edge of the part 16 is a vertically disposed leg 15 which merges into the bottom edge of part 12 and not only provides for supporting part 16, but further provides for spacing the rear edge of part 16 from the forwardface of part 12. The part 16 is of greater width than part 13 and of less width than part 12.

The forward edge of part 16 merges into a rearwardly directed angle shaped flange which is disposed below part 16. The flange includes a horizontal portion 17 and a vertical portion 18. The portion 18 abuts the lower face of part 16, is integral with and extends inwardly from the forward edge of part 16. The rear of portion 17 terminates in the top of portion 18 and the latter provides a vertically disposed supporting leg for and which is inset with respect to the forward edge of the part 16. The legs 15 and 18 support the cushion formed by the part 16 in spaced relation with respect to the sill 10. See Figure 1. Positioned upon the upper face of the cushion 16, is a substantially inverted U-shaped supporting memher or setting block 19 which includes upon the upper edge thereof, a cushioning layer which may be formed of fabric or leather, and which is indicated as at 20, and which is adapted to receive thereon the lower edge of a plate glass or the like 21. These supporting members 19 are arranged in spaced relation upon the cushion portion 16 and vary in number, according to the size and weight of the glass. i

In order to provide means upon the outer side of the plate glass 21 for holding the same upon the cushioning member 19 and leather support 20, I provide the usual and ordinary type of outer moulding 22 and which has extending at an inclination therefrom suitable fastening elements in the form of screws 23 which in turn extend between the supporting member 19 and through slots 24 provided upon the vertical portion of the back member 12 whereby the inner end portion of the screw member 23 may be embedded in the backing stop.

The sill covering which extends along an appreciable distance upon the upper side of jected to the weight of the plate glass 21. The

outer moulding has its inner lower edge arranged in contacting engagement with the vertical portion 18 and below the horizontal portion 17 of the rearwardly directed, angle shaped flange, and as shown the flange 9, the

vertical portion 18 and the inner lower edge of the outer moulding interlock to provide a water-proof joint and prevent movement of the parts.

A saving in material is had when the covering is formed, due to the fact that it does not necessitate the making of part 1 of a width to have the flange 9 thereof engage against the rear face of the vertical part 12 of the back member 12, but of a width to have the flange 9 coact with the leg 18 which is arranged forwardly of the vertical part 12 and at the front of the part 16 forming the cushion.

In Figures 4 to 7 the form of back member employed is slightly different from that shown in Figures 1 and 2. The differences reside solely in the shape of the forwardly directed flange 27 at the top of the part 12 and the shape of the depending flange 28 at the forward side of the part 16 of the back member 12. The flange 27 includes a depending, forwardly inclined part 29 which merges into a forwardly directed flat part 30 the latter terminating in a vertical part 31 corresponding to part 13. The flange 28 includes -a vertically disposed, depending part 32 which terminates at its lower end in a rearwardly directed part 33 arranged parallel to and spaced from the lower face of part 34 corresponding to part 16. The positioning of part 33 spaced from part 34 providesa pocket 35. Otherwise than that as stated the form of back member 12 illustrated in connection with Figures 4 to 7 is the same as that shown in Figures 1 and 2.

The covering shown in Figure 4 is employed in connection with a head jamb 36 having secured against its lower face a substantial distance from its front a depending backing stop 37 against which is positioned the back member 12. The covering includes a vertical part 38 and a horizontally disposed part 39 projecting rearwardly from the lower end of part 38 and arranged against the lower face of jamb 36 forwardly of and spaced from the vertical part 12 of member 12. T he. part 38 is slightly less in height than and is positioned against the front of jamb 36. The part 39 at its inner end is formed with a dependthe sash and covering together.

ing'flange 40 formed of a vertically disposed leg 41 and a forwardly directed, horizontal leg 42 atthe lower end of leg 41. The leg 42 is spaced from part 39 to providea pocket 43. The flanges 28 and 40 intere'nga'ge with each other which provides for the interlocking-of The front moulding of the sash .is indicated at 44 which has its upper end opposing part 39 and concealing the interlock. A top moulding 45 conceals the upper portion of the part 38 of the covering.

The form of covering shown in Figure 5 is formed for use in connection with a central jamb indicated at 46. The covering includes the forward part of the bottom of the jamb 46. The parts 48 and 49 extend rearwardly from the top and bottom respectively of part 47 of the covering; The rear of parts 48 and 49 are provided respectively with upwardly and downwardly directedflanges 50, 51.

The flange 50 includes an upwardly directed vertical leg 52 terminating at its upper end in a forwardly directed horizontal leg 53 spaced from part 48 to form a pocket 54. The flange 51 includes a depending vertical leg 55 terminating at its lower end in a forwardly directed, horizontally disposed leg 56 spaced from part 49 to provide a pocket 57 Arranged against the rear portion of the top and bottom of the jamb 46 are backing stops 58, '59 respectively, against which are positioned backing members 12 which are oppositely disposed. The flanges 50, 51 interengage with the flanges 28 of the backing members for the purpose of interlocking the covering in position. The front or face mouldings of the sashes are indicated 60, which abut parts 48, 49 and conceal the interlocks for the covering.

The form of covering shown in Figures 6 and 7, comprises a vertical part 61 for positioning against the front ofthe sill 62, a rearwardly extending, horizontally disposed part 63 extended from the top of part 61 for mounting on the forward portion of the top of sill 62 and a rearwardly extend-ing horizontal part 64 at the lower end of part 61.

- he part 61 is of a height greater than the front of sill 62 and depends below the bottom of the latter. The part 64 has its inner portion upset, as at 65 to abut the lower face of sill 62. The part 64 at its rear is formed with a depending, vertically disposed flange 66 which abuts a support 67 for the sill. The part 64 constitutes what may be termed a resilient latch.

The part 63 has its rearformed with a flange 68 consisting ofan upstanding vertical leg 69 terminating at its upper end in 'a forwardly directed, horizontally disposedleg 7O spaced from part 63 and providing a pocket 71.

The flanges 28 and 68 interengage to interlock the covering to the sash which is post tioned against the back stop 72 secured upon the rear portion of the top of the sill 62. The front moulding or face of the sash is indicated at 73 which abuts part 64 and conceals the interlock.

The plate glass, indicated at 74, in Figures 4, 5 and 6, is clamped between the flange 27 and the front moulding of the sash and has its lower end mounted on a setting block referred to generally at 7 5 Figure 6.

The forms of coverings shown in Figures 4, 5, 6 and 7 will also provide for a saving in material, due to the width of that part of the covering provided with the flanges for interlocking with the forward end of the back member.

It will thus be noted from the foregoing description and accompanying drawing that a person within the store window when washing the plate glass will cause water to drain downwardly upon the inner side of the glass and into the gutter formed by the flange upon the upper edge of the back member and flow or drain through the ventilating or drain holes, or openings provided therein and will thence find its way between the backing member and the outer or face moulding through the opening provided adjacent the lower edge thereof whereby the water or moisture will be drained outwardly and upon the sill covering in order that no moisture will be allowed to stay between the back member and outer moulding which would deteriorate or destroy the ventilating sash, and further that the covering will act to protect the sill as the water passes off the same, and that the sill will also be protected by the covering from rain, sleet or snow.

It is thought the many advantages of an interlocking sill or jamb covering, in accordance with this invention can be readily understood, and although the preferred embodiment of the invention is as illustrated and described, yet it is to be understood that changes in the details of construction can be had which fall within the scope of the invention as claimed.
